论文摘要
我们构建了一类强耦合$ su(n)$ $ $ \ $ \ MATHCAL {n} = 4 $ SEMM的重力双重偶,在Infinite $ n $和渐近温度$ t _ {\ infty} $上,在固定的SchwarzsChild Blackgenti所得的散装几何形状是流动类型的,使我们能够在强耦合时测量鹰辐射。传出的鹰磁通是无量纲比率$τ\ equiv t _ {\ infty}/t _ {\ mathrm {bh}} $的函数,并且似乎是$τ$的非单调性。目前,我们对这种行为没有现场理论的理解。
We construct the gravitational dual of a one-parameter class of states of strongly coupled $SU(N)$ $\mathcal{N}=4$ SYM at infinite $N$ and asymptotic temperature $T_{\infty}$, on a fixed Schwarzschild black hole background with temperature $T_{\mathrm{BH}}$. The resulting bulk geometry is of the flowing type and allow us to measure Hawking radiation at strong coupling. The outgoing Hawking flux is a function of the dimensionless ratio $τ\equiv T_{\infty}/T_{\mathrm{BH}}$ and appears to be non-monotonic in $τ$. At present, we have no field theory understanding for this behaviour.
